\ I Application filed March 24, 1913. Serial Nol 756,288.

To all whom it mag concern: Be it known that 1, WILLIAM J. S RIT- SCHER, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Paper-Pinning Machines, of which the following is a specification.

An object of my invention is to provide a paper pinning machine including auto: matically operable means for inserting a pin or similar member through two or more,

pieces ofpaper, etc., such for two sheets of letter paper, letter paper and a check. I

A furtherobject of the present invention is to provide in a machine of the character described, means for automatically feeding pins from a supply of pins into position to be acted uponby the means for inserting successive pins through pieces of paper,

example, as or'a sheet of J illustrate an application of my invention:

: Plunger 7 is-provided with 10 enteredin a slot 11 of member 5. Con- Figure 1 is a part side elevational view and a part vertical sectional view, the section being taken on line II of Fig. 2; Fig. 2 is an end View;

Fig. 3, is a part plan and a part horizontal section,the section being taken on line III-III of Fig. 1;

Fig. 4 is a' vertical sectional view taken on line IV.IV of Fig. 1 looking in the direction of the arrows;

Fig. 5 is a similarview of. Fig. 4; and

Figs. 6, 7, and S are sectional diagrammatic views particularly illustrating the different positions assumed by the combined taken on line V- V pin pusher and carrier employed int-the Located within the hollow member 5, and Y adapted to be reciprocated \therein, rpm vide a spring controlled plunger 7 with the spring 8 interposed between the upper end of member 5 and a head!) of'the plunger.

etc. In the accompanying drawings, which.

a projecting lug nected with the plunger 7 by means of a threaded connecting member 12, I provide a movable die-block or paper crimping member 13. Member 13 is adapted to co-act with a stationary block 14 to crimp or emboss the paper or other material through which a pin is adapted to be inserted.

Plunger 7 is provided with" a hollow space i 15 adapted to receive a spring 16 having an end bearing against the upper wall of the space 15 and its opposite end bearing against u'ng rods 17 extending downwardly therefrom, and having their lower ends respectively connected with the slotted arm 18 of a bell-crank lever 19 by meansof a rod 20. As illustrated and as preferred, I employ two bell-crank levers 19 fulcrumed on a'cross rod 21. The opposite arms 22 of the respective bell-crank levers 19 are each connected with a combined, reciprocating 85 pin pusher and carrier 23 by means of rods or connecting links 24, 25, and 26. lFhe member 23 is provided with a slot 23 adapted when the member 23 is on its return stroke to receive and engage th head of a pin for the purpose of withdrawing a pin.

free ofthe roll of paper.

' From the foregoing, it will benoted that the movement. or. reciprocation of the combined pin pusher and carrier 23 1s efiected' by the vertical movement of the plunger 7, and that during the downward or forward troke of the plunger 7 the combined pusher and. carrier 23 is moved from the Fig. l to 101 position shown in full lines n the position shown in dotted l nes.

Located between and projecting up into the space between the members 2 and 3 of the housing, I provide a plate 27 havmg acentrally disposed upwardly projecting 105 member 28, the latter constituting a track or race-way for the combined pusher and carrier 23,- and also serving as a support for the shafts or rods. 20, 21, and 29. Member 28 is alsoprovided with a slot 30' adapted to 110 the projecting lug receive the rod 20 connecting the lower ends of rods'17.

31 designates a roll containing a supply of pins which are'adapted to'be automatically fed into operative position to be engaged by the combined pin pusher and carrier. The means shown for moving the strip 32, containing the pins 33, into the a desired positions, include a dog 34 carried 10 on one of the connecting rods 17, 'a ratchet 35 nd gears 36 respectively mounted on rollers 37 and 38, and idlers 39 and 40. I The dog 34, during a downward stroke of the plunger and the connecting rods 17 engages with the ratchet 35 thereby turning thesameand the coacting gears 36 together with the rollers 37 and 38, thus feeding the strip forward to bring a pin into operative position to be engaged by the combined pusher and carrier 23 during its backward movement. The position of the pin, while 4 in its strip and just prior to being engaged @by the combined pusher and carrier, is shown in Fig. 1. As illustrated, the pin is located slightly above the reciprocating member 23, and in order that said member may engage the head of the pin during its backward travel,- it is necessary to raise member 23 slightly. ,To accomplish this, I' provide a vertically movable member 41 adaptedto extend upwardly through the member 28 and strike the member 23, as particular'lyillustrated in Fig. "6, thus raising the member 23 to have an edge of'the latter 85 engage a head of a pin.

. The lower edge 42 015 member 41 is-in clined and rests upon a horizontally disposed member 43, which latter atone end is formed wedge-shaped as indicated by 44. Located at the opposite end of member 43,

I provide a sprin controlled pivoted head or dog 45 dispose in the path of travel of. the rod 20 and adapted to be engaged thereby during the vertical movements of said 45 rod, 46 designates the spring controlling the dog 45, and it will be noted that during .a downward movement of rod 20, said rod will strike the dog 45, but a sliding movement will not be imparted to member 43 50 .until the rod 20 makes contact with the dog 45 on its return or upward traveL.

The pin grasped by the member 23 is carried rearwardl and drops into the position shown in Fig. ready to be engaged by the combined pusher and carrier on its next succeeding forward stroke, and passed forward and through the crimped portion of the j sheets of paper, etc., asparticularly shown by Fig. 8. r

As will be readily understood, theconstruction herein disclosed is operative to effect a transfer of'a selected pin from a pin strip to a position in which the several pieces of paper are fastened together, this operation' being completed in such manner .as to by the plunger for reciprocating the pusher,

.rod connecting said leverandplunger, and

leave the pin and strip unimpaired. In providing this operation, the selected pin is first withdrawn from the strip, leaving the latter unbroken and thereby permitting of the use of feeding rolls 'on opposite sides of the path of the reciprocating element, an effect 'whi'chwill prevent sagging of the strip and place the pins successively in proper position to have their heads engaged by the reciprocating element. As will be understood, the completion of the movement of the element in the direction of its pin withdrawing movement leaves the pin free to pass from holding engagement with the element by its head. dropping through the slotted passageway 23 and'be positioned in advance of the element ready to be driven into the pieces through the crimped portions when the element is moved in its opposite direction.
